Abstract: A process for joining components and assembly units of rail-borne vehicles by bonding is described, in which the use of an adhesive, which produces fatigue strength but cures more slowly, is combined with the use of an adhesive that ensures sufficient strength for handling in a short time, wherein complicated design of the bonded joints as well as the need for a large amount of devices are to be avoided, manufacturing tolerances are to be equalized, and defined minimum bonded gap widths are to be maintained. Furthermore, the wetting by the adhesive shall be limited to selected joining surfaces, without having to remove and dispose of the edge limitation.

Abstract: The invention relates to a tilt control for the superstructure of a rail vehicle, that includes a transversal acceleration sensor and a tilt control device controlled therefrom for tilting the superstructure along its longitudinal axis in relation to the running gear or the bogie supporting the superstructure. A low-pass filter is connected in the signal path between the transversal acceleration sensor and the tilt control device. In order to at least amply compensate the operation time of the low-pass filter, a steady state member is connected in the signal path between the transversal acceleration sensor and the low-pass filter, whose output signal is selected at least in the middle segment of a predetermined measuring value of the transversal acceleration values to be detected in such a way that the transversal acceleration in the superstructure remains almost constant in said segment.

Abstract: In a method for the probabilistic estimation of measurements, based on a measurement signal in which an interference signal is superimposed on the value to be measured, the measurement signal is sampled at specified chronological intervals. A defined measurement range associated with the value to be measured is divided into discrete values and a model is formed of a process on which the measurement signal is based with discrete states that correspond to the discrete values of the measurement range. In the model, a probability value of the occurrence of each state is assigned for each sampling time, and the value to be measured is determined on the basis of the probability value of at least one state in this model. In addition, for each state of the model at a sampling time, a probability for the state to remain in its current state is determined, as well as a probability for the state to change to another state by the next sampling time.

Abstract: The invention relates to a drive unit for electric rail vehicles, wherein the hub (7) of a greater wheel (6) driven by an electric traction motor (1) via a pinion shaft (4) forms a hollow shaft stub which surrounds the shaft (9) of a wheel set with a defined play. By inserting a coupling (11) which is radially rigid but allows transverse and angular movements, the motor torque is transmitted to one of the wheels (10) of the wheel set. The axial mobility of the coupling (11) should not have any disturbing restoring forces or resilient forces. Therefore, the hub-side coupling half (11b) having a curved-teeth-shaped external toothing engages the wheel-side coupling half (11a) which is provided with a straight internal toothing. The wheel-side coupling half (11a) is detachably connected via coupling supports to the inside flank of a disk wheel (10) and the hub-side coupling half (11b) to the hub.

The body rests on the cars and swings out on the air spring. There is also an emergency spring which has a core. Guide and damping devices are further disposed between the body and the cars.

The friction plate is linked to the core of the emergency spring or the base point of the air spring to form a connection to the cars in a longitudinal direction for suppressing the sway of the cars.
